Question

The diameter of a circle is 20m
Find the circumference to the nearest tenth

Answer 1

C = 62.8 m

Explanation:

The circumference formula is C = πd.

Here d = 20 m. Therefore, the circumference of this circle is C = (20 m)π.

To the nearest 10th, we round off C = (20 m)(3.14159) = C = 62.8 m
